Application led February 2, 1915. Serial No. 5,687.

provide a device of the character described which is simple in construction and comparatively cheap to manufacture', contrasting in this latter feature with the many known devices for obtaining the same result,

which owing to their complicated nature` necessitating much work on the rail ends, are unpractieable from a commercial point of view. j j

l attain my objects by means of interlocking the rail ends in a simple andretfeetive fashion, preventing any respective vertical deviation thereof, and by means ofcutting away the rail ends diagonally in respectto the longitudinal axis of the rails, whereby.

the wheels passing from one rail end to the adjoining one will. do so gradually and not eut away diagonally in respect to their 1onstrike suddenly against the edge ofthe rail end at the farther side of the space usually left between adjoining rails to allow for their expansion.

Reference will now be had to the accompanying drawing, in which:

Figure l is a side elevational view of a rail-joint constructed according to my invention, hidden parts being indicated by dotted lines; Fi r. is a )lan view of the same" Figs. 3 and t are side elevational views of the rail ends, one being the complement of the otl1er.

Similar reference characters refer to similar parts throughout the several views.

Referring more particularly to the drawing, 5 and t3 are rail ends the adjoining faces of which are cut away diagonally in respect to the longitudinal axis of the rails, as shown at 7 and 8, respectively. lln the front edge of the web of the rail end 5, at about midheight, l provide a horizontal groove v9, open at the front, and on the front edge of the opposite rail-end 6 l provide a tongue 10 registering with the groove 9 and ttng closely therem, so that when the two rail ends are secured together, it will prevent their vertical movement in respect to each other. j y The front edge of the tongue 10 and the rear wall of the groove 9 are also formed diagonally in a plane parallel with the front` edges of the rails so that the rail ends can be eut out, 'immediately after passing the rolling mills, by one 'diagonal movement of a shearing machine.

f rlhe rail ends eonstructed'according to my invention may be joined together in any known way, such as by means of fish plates 11 and screw bolts 124.i

The usual space betweenthe meetingrail ends, to allow for the expansion of the rails,

gitudinalA axis, a horizontal groove formed in the front edge of the web of one, rail end and a tongue closely fitting into said groove formed on the front edge of the web of the other Vrail end, said groove adapted to enage said tongue and lock said -rail ends rom a respective vertical movement when joined together, the front edge of said tongue and the rear wall of said groove being cut away diagonally in a plane parallel to the front ends of said rails, substantially as and for the purpose set torth.-
